Abstract

Provided herein is: a method of efficiently manufacturing a curable silicone sheet with excellent flatness and uniformity, containing a curable particulate silicone composition with excellent handling/workability and curing properties; and a method of manufacturing a laminate body containing the curable silicone sheet. A method of manufacturing a curable silicone sheet having hot melt properties, comprises the following steps: 1) a step of mixing organopolysiloxane resin fine particles, a curing agent, and a functional filler; 2) a step of kneading while heating and melting the mixture obtained in step 1); 3) a step of laminating the heated and melted mixture obtained in step 2) between films provided with at least one release surface; and 4) a step of stretching the laminate body obtained in step 3) between rollers to mold a curable silicone sheet having a specific film thickness.
